Python - File Reading and Writing Strategies

What will be the output of this code snippet when reading a large file in chunks?

with open('largefile.txt', 'r') as f:
    chunk = f.read(5)
    print(chunk)
    chunk = f.read(5)
    print(chunk)

APrints first 5 characters, then next 5 characters of the file

BPrints the entire file twice

CPrints only the first 5 characters twice

DRaises an error because read() needs no arguments

Step-by-Step Solution

Solution:

Step 1: Understand read(size) behavior
Calling f.read(5) reads 5 characters from the current file position.
Step 2: Reading twice moves file pointer forward
First read gets chars 1-5, second read gets chars 6-10.
Final Answer:
Prints first 5 characters, then next 5 characters of the file -> Option A
Quick Check:
read(5) reads 5 chars sequentially [OK]

Quick Trick: read(n) reads next n characters sequentially [OK]
